2. The display panel of claim 1, wherein the light transmittance of the black adhesive layer is in a range of 48% to 71%.
3. The display panel of claim 1, wherein the display panel is absent of any polarizer.
9. The display panel of claim 8, wherein the orthographic projection of the color filter on the base substrate covers an orthographic projection of the apertures defined by the black matrix layer on the base substrate.
15. The display panel of claim 1, wherein the black adhesive layer has a thickness in a range of 10 μm to 100 μm.
16. The display panel of claim 1, wherein the particles have an average diameter in a range of 10 nm to 500 nm.
17. The display panel of claim 1, wherein the particles comprise a light absorbing black material.
18. The display panel of claim 17, wherein the black material comprises carbon or a black metal oxide material.
19. A display apparatus, comprising the display panel of claim 1, and an integrated circuit connected to the display panel.
